To cilia/1.0m itmag concern: I

Be it known that I, NELSON NYBEKG, a citizen of the United States, and a resident of Miami, in the county of Gila and State of Arizona, have invented a new and Improved Blower for Signaling Devices, of

which the following is a full, clear, and ex-' act description.

My invention has for its object to provide ,a blower for signaling devices, consisting of a seat having upper and lower compartments divided by a partition having a valve opening, with which a valve cooperates, there being springs for holding the partition extended upwardly and for holding the top of the upper compartment extended upwardly, so that as the occupant of the seat .is moved up and down by the unevenness of the road over which the automobile travels, air will be drawn in through valves in the bottom of the lower compartments and this air will pass through the valve opening in the partition to the upper compartment, where it will be compressed to be fed through a pipe to a pneumatic signal which is controlled by a valve in the pipe.

Additional objects of my invention will appear in the following specification, in which the preferred form of my invention is described.

In the drawings, similar reference characters refer to similar parts in all the views, in which- Figure 1 is a perspective view, showing how my blower for signaling devices is attached to an automobile; Fig. 2 is a view showing my seat with the springs compressed and before air is compressed in the compartments of the seat; Fig. 3 is a sectional view, showing the main valve and a. safety valve; Fig. 4 is an enlarged sectional elevation of the seat; Fig. 5 is a view similar to that shown in Fig. 4, but with the springs compressed and the valves open; Fig. 6 is an inverted plan view of Fig. 4; Fig. 7 is a perspective view, showing one of the valves; and Fig. 8 is a sectional view showing the pneumatic signal.

By referring to the drawings, it will be seen that the seat 10 is constructed to be disposed on the seat 11 of the automobile 12, the seat 10 having ribs 13 spaced apart at its bottom 14, so that air may pass to the valve openings 15 in the bottom 14 of the seat. Secured to the bottom 14 there are plates 16, having valve seats 17, which register with the valve openings 15, valves 18 being hinged at 19 to "the plates 16 for seating on the valve seats 17jto close commu-nication through the valve openings 15*. The seat 10 has a top 20, the top 20 and the bottom 14 being connected by a flexible in'emb'er 21, which may be a continuation of the top 20, which is preferably constructed of flexible material. Disposed in the seat 10 between the top 20 and the bottom 14 there is a partition 22, having a valve opening 23, a plate 24 being secured to the partition 22, this plate 24 having a valve seat 25 which is commanded by a valve 26 hinged to the plate 24 at The partition 22 is held extended above the bottom 14 of the seat 10 by the springs 28 and the top 20 is held yieldingly above the partition 22 by the springs 29. It will therefore be seen that before air has been compressed into the seat 10, the springs will be compressed and the top 20 of the seat will be disposed close to the bottom 14, but when the automobile is driven, the little unevenness of the ground will move the person occupying the seat 10 upwardly, which will cause the air to enter the compartment between the bottom 14 and the partition 22 through the valve openings 15. This air will accumulate in the said lower compartment and with the continued movement of the automobile, the air will be forced through the valve opening 23 to the upper compartment between the partition 22 and the top 20 of the seat.

In the upper compartment, there is an opening 30 in the flexible side 21 of the seat 10, in which is secured a pipe 31. This pipe 31 leads to a bracket 32, having an opening 33, with which the pipe 34 communicates, the pipe 34 leading to a safety valve 35 which may be of any ordinary construction. A pipe 36 connects the opening 33 in the bracket 32 with an opening 37 in a bracket 38, this bracket 38 having a guideway 39 for a valve 40, which has an opening 41, which permits the compressed air to flow from the pipe 36 to the pipe 42 when the valve stem 43 is pressed downwardly against the resiliency of the spring 44. The pipe 42 leads to the pneumatic signal 45. It will be understood that the brackets 32 and 38 may be positioned on the car as may be desired, so that the valve stem 43 may be pressed down by pressure of the foot, the knee or the arm, to suit the convenience of the operator. A sleeve 45 is mounted on the signal for regulating the sound of the signal.

Having thus described my invention I claim as new and desire to secure by Letters Patent In a device of the-character described, a seat having a top, bottom and sides, a partition in the seat disposed substantially parallel with the top and the bottom, there being a valve opening in the partition, a valve commanding the valve opening, there being a valve opening adjacent the bottom of the seat, there being a valve commanding the Copies of this patent may be obtained for compression when a person sits on the seat.

In Witness whereof I have signed my name to this specification 1n the presence of two subscrlbmg witnesses.
